Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithmss" » "modified multiobjective optimization algorithmss", "modified multiobjective estimation algorithms", "modified multiobjective optimization algorithms"
"modified lighting estimation algorithm" » "modified caging estimation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified lighting estimation algorithm") OR ("modified multiobjective estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified lighting estimation algorithm\") OR (\"modified multiobjective estimation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified lighting estimation algorithm ) OR ( modified multiobjective estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified lighting estimation algorithm") OR ("modified multiobjective estimation algorithmss"))*.
